Application filed Noivembei 1. 1906- Serial No. 344.459.

Be it known that I, FORREST'XVHITnwa citizen of the United States, residing at Euclid, in the county of Cuya-hoga and State. of Ohio, have invented new and usefu l 1 m which the following is a specification.

The invention relates to machines for outt has for its object to'provide an adjustthe saw so that it will saw straight.

A further object is to provide means for raising and lowering the saw, and also improved traction means for driving the machine over the ice and for steering the same,

rudder. 7 p

Various other objects and advantages will. appear from the following description and Inthe drawings, Figured is aside eleva tion of the machine. Fig. 2 is a plan view thereof. Fig. 3 is a longitudinal vertical section.

The machine is motor driven, the engine or motor being indicated at 6, mounted upon apair of runners 7 which runners form substantially the sole supporting means for the apparatus. The vmain driving shaft, driven by the motor, is indicated at 8. This is mounted in suitable supportsvon the frame eared by means of a sprocket 9, chain be t 10', and

which is located at about the middle line' of the machine in front of the runners and the motor.

The saw arbor or shaft 12 is carried in a boxing 14 which is hinged by a bolt 15 and ears 51. to the front end of a swinging frame which are bowed over and pivoted upon the boxes of the .main shaft 8, as indicated at 17, and at the right side said frame is continued to the rear to connection so that the saw may be to the ice by. swinging the frame on the main shaft as a pivot. By this means, too, the saw arbor is at all times the same distance from the shaft, so that the gearing is'not interfered with. The skeleton frame is an advantage because it avoids the lodgment of snow and ice thereon In advance of the saw. a gage bar and 5 support 19 is provided. This is connected line with the hinge gage bar. slightly above the ice.

arbor by means of spring bars 20 so that they will allowa certain amount of lateral spring. ed by a similar bar 21, at t-he opposite side The gage bar is also support',-

which are flattened vertically of the machine, and this bar is hinged 'at its rear end, as at 22, to the corresponding sidebar of. the frame 16', the hinge 22-bei 1nbolt 15, so that the w ole' supporting frame of: the saw may be flexed on said hinges as a pivot.

The gage bar 19 is clamped old the i This makes it possible to readily-adjust the depth of cut byraising or lowermg the gage bar 19, this ac- .eflected by means of an'uright' the rod 24 the gage bar 19will be to and'rests upon shoes 27 which slide on the surface of the ice and which support" said The shoes have kerf plates 27, oneof which slides in the preceding kerf and the other of which travels on the ice.

A saw guide is supported upon the gage bar 19 for the purpose of guidingand steadying the saw; said guide is indicated at 28 and. has fingers 29 which press'against the opposite sides of the edge of the saw and which when theguide bar is sprung'one way or the other will sp'ringthe cutting edge of the saw so that it will cut in any course,v without binding; The arms 2-0 and 21 are made of spring metal so thatthey will spring sidewise and allow the saw guide on the saw to bend the cutting edge of the saw so that it will saw its waythrough, without binding The shoes 27 may be. adjusted lengthwise on the bar 19, according to the width of the strip to be cut, acting as leaders by being placed at equal distances on opposite sides of the saw, suchdist ance being equal to the width of the strip to be cut.

The driving means consist of a pair 01 spud traction wheels 30 which are carried on a shaft 31 mounted in bearing boxes 32 which are slidable up and down on inclined supports 3-3 at the rear end of the runners 7.

. The traction wheel shaft has a gear 34 meshing with a pinion 35 on a cross shaft 36 whichv is also carried in sliding boxes 37 on the supports 33 and'said shaft 36 is driven from the main, shaft. 3 .by "means of a sprocket g chain helti fie' and spree-listed on-theend of l the shaft 36, the fatter Wheel being prefershiy Barge-to form a fly-Wheel.

For the purpose of facilitating theturn of the-machine at the end of a strip, there is provided aisharpenedpivot pin 47 which is car tied at. the middle of the machine by an anguiar cross bar 18 pivoted at .49 to the runners, Ween thesarne, and provided atone side 1 h enupwardly- Xtendinglev'er 50, Whereeo a the pivot pin may he raisedor lowered.

When turning the machine, "the traction Wheels and rudder and also the frame contraining sew and gage bar are raised free from g the ice, so'thet the machine is carried by the i runners "Z The niachine is then moved side-.- wise distance equal to the Width ofthe next strip to be cut, and the pin is then pushed down into the ice to forms pivot'for the machine, Which can then be swung around a j r l E l half turn. The pivot pin then raised and the traction Wheels and rudder and the frame containing saw and gagebar are lowered for the next out.
